Section 2: DESeq2 analysis
DESeq2 analyses steps
This section uses the counts data (for selected datasets) generated in Section 1 to differential expression (DE) analyses using DESeq2. Breifly, the counts data is imported in R, batch corrected using ComBat_seq, DE performed for various contrasts using DESeq2, results visualized as volcano plots, and cell enrichment performed using PlacentaCellEnrich.
